The present invention is a method of preparing a tuber for consumption, with the tuber having added food ingredients in the tuber. The tuber is thoroughly cooked. The tuber is frozen to provide rigidity about the skin of the tuber, while leaving a portion of the flesh unfrozen. A portion of the flesh of the tuber is removed either prior to or after cooking. The desired added food material is inserted through a hole in the skin and into the void where flesh of the tuber was removed. The tuber may then be completely frozen for later preparation and consumption.
